WELL CASING. j

Application filed April 23, 1923.

To all whom it may concern: Y

Be it known that I, FRANK J. GREEN, a citizen of the United States,residing at Gibbon, in the county of Bualo and State of Nebraska, haveinvented certain new and useful Improvements in Tell Casings, of whichthe following is a specification, reference being had to theaccompanying drawings.

Ihis invention relates to certain improvements in well casings and it isan object of the invention to provide a novel and improved casing ofthis general' character comprising a plurality of sections adapted to besuperimposed one upon the other together with means for maintaining saidsections in assembled relation.

Another object yof the invention is to provide a novel and improvedcasing of this general character wherein that portion thereof below thewater line is provided with openings to permit ingress of water withinthe casing. Y

The invention consists in the details of construction and in thecombination and arrangement of the'iseveral parts of. my improved wellcasing whereby certain 1mpor` 4tant advantages are attained and thedevice rendered simpler, less expensivev and .other-y wise moreconvenient and advantageous for use, as will be hereinafter more fullyset forth.

The novel features of my j hereinafter be definitely claimed."

better understood, I will now proceed to describe the same withreference to ythe accompanying drawings, wherein :--l

Figure l is a sectional view illustrating a well casing lconstructed inaccordance with an embodimentof my invention and in applied position;. l1 Figure2 is Va view inep'erspective illustrating a pair of adjacentsections comprised in my improved casing as hereiny disclosed; and

Figure 3 is a fragmentary horizontal sectional view on an enlargedvscale, taken through one of the sections. v

My improved casing as'he'rein disclosed comprises a plurality ofsections S superimposed one upon the. other and the ends of the sectionsare similarly beveled as at 1 to provide and assure a self-aligningtight joint when the sections are assembled. Each of the sections S isto be of dimensions preinvention. will Serial No. 634,028.

ferred with its walls of material .thickness and the casing in itsentirety is intended to be sunk into water bearing gravel below all soiland quick sand to a depth required to furnish the desired quantity ofwater. The walls of the sections S comprised in the cas# ing above thewater line orfextending through the soil and quick sand are imperfora'tewith theexception of the end openings in the faces thereof to behereinafter referred to. l

The walls of the sections S below the waterV level or within the waterbearing. gravel have disposed therethrough the horizontally disposedcores or openings 2, each of said openings or cores 2 being relativelynarrow in a direction transversely of the wall in which it is formed andcomparatively long in a direction longitudinally of said vwall wherebythe maximum diameter of said ings is slightly larger than the inner oreduction end of such core or opening, the

walls of said core or opening being tapered from the induction end tothe eduction or inner end. By this formation of the openings-2 theaction of the pump (not shown) associated with the assembled or appliedcasing is materially increased as the requisite lifting of the waterwill be facilitated. j In practice, Il find it preferable to have n theaggregate area of the eduction or inner In order that my invention maybe theendsof `the 'cores or openings 2 of each face or wall of a sectionS equal to approximately fifteen per cent of the area of said wall orface. Disposed through the openings or cores 2 in adjacent ends of thesections S below the water line are the wire ties S, sim- -ilar ties 3lbeing also disposed through the openings a hereinbefore referred to inthe adjacentends of the sections S below the water line. The ties 3associated with the upper core or perforate section and the `flowerimperforate section are directed llO through the openings or cores 2 andsuch water collected may be pumped or raised in any ordinary orpreferred manner. As the pumping or lifting mechanism forms no part ofmy present invent-ion it is not believed necessary that the same bedescribed or illustrated.

Each ofthe sections S is molded or cast in one solid piece and embeddedin the upper and lower portions of each of the sections S are thereinforcements 4 preferably metallic.

From the foregoing description itV is thought to be obvious that a wellcasing constructed in accordance with my invention is particularly welladapted for use by reason of the convenience'and facility with which itmay be assembled and operated, `and it will also be obvious that my.invention is susceptable of some change and modification withoutdeparting fromthe principles and spirit thereof and for this reason l donot Wish to be understood as limiting myself to the precise arrangementand formation of the several parts herein shown in carrying out myinvention in practice except as hereinafter claimed.

l claim l A Well casing comprising a plurality of sections adapted to besuperimposed' one upon the other, the Walls of each of the sectionsbeing of material thickness, reinforcements embedded within the walls ofeach of the sections adjacent the' opposite ends thereof, opposite endportions of each of the sections being similarly beveled to provide amale end and a female end to assure a selfaligning tight joint when thesections are assembled, thev upper sections of the casing having thewalls imperforate with the exception of openings in the opposite endportions thereof, the lower section having openings disposed through thewalls thereof substantially at right angles to the axis of said section,each of said openings being relatively narrow in a directiontransversely of the section and comparatively long in a directionlongitudinally of said section, each of said openings` being taperedfrom the outer end to the inner end thereof, connecting ties disposedthroughthe end openings of the imperforate sections to hold the same inassembled relation, and ties disposed through the upper tapered openingsof the lower section and the lower openings in the adjacent imperforatesection to hold said two sections in assembled relation.

lfn testimony whereof l hereunto affix my signature.

FRANK J. GREEN.
